Applica-tion sied, June 22, 192,5J se'riaiivo'. 38,853, ansia Germani April 3,1925] f f vWith the known constructions of theprcrar jrying beams forA the worin gear actuated spindles or cops of spinning, .twisting andthe like 'machines the bearings for the 'driv Y ing shaft of the spindles are normally cairied on Y.screw bolts by means of `a *groove or the like, which' requires a careful adjustment if the rvmachine is .to `run smoothly. It, friequent'ly occurs lioweverfthat `Ythe screw vbolts are loosened by the vibrations of the carry ing beam whereby the actuating shaft becomes loose andl can bev displaced thereby endangering dles or cops. Y y

According to this present invention these .deficiencies are avoided'by thev ends oftwo adjoining beam yca'sings being rigidly con# nected with each other and constructed as a common supportV for. the bearings of* thev actuating shafts. The actuating shafts are` thus completely stationarily supported whereby'the greatest possible eXactness forv the spindle actuation is'obtained.y The ball bearing is thus forming theonly. connection tothe outside or to the adjacent .beam re- .spectively and is at the same time used for v' centering the casings with relation to each other. u

In the drawing illustrating two preferred embodiments of my invention Fig.v 1 is a horizontal .section through the bearing point casings, l Fig.` 2 the embodiment.`

The end faces 1, V2`of the two adjoining samek section through another bearing beam casings 3:, 4 are rigidly held together by the screw boltsv 5 and after such attachment providedv with the bore 6 for the Y' reception'ofy the ballbearings 7. The studs 8 of the inner member'of theball lbearingsv 7 are used for the connection of the actuating screw spindles 13 are attached to eachother The attachmentv -according to requirement. is effected by the screws '5. Inorder that the beam sectionsmay `be precisely joinedV lto each other, the end faces 1and2'ofjtwoV the safe actuation ofthe spin-r of two adjacent bearing beam'.v

1 1,661.2@ PATENT- adjoining beam lsections are Lverycarefully Y been connected with leach other by the screw bolts 5. The ball -rbearing 7is mounted in 'the opening. 6 with a tight fit. The main shaft 9 is 'not extending through several ing shaft sections. j

To this end the inner lmember V14 of the ball bearing 7 isprovided with two fiat studsv 8 projecting into corresponding recesses l5 of the shaft sections 9. The' shafts 9 are workedand the*` hole 6., vreceiving.'the lballv bearings 7' 1s bored after the sections having f lockedto thestuds 8 by slidingsleeves'lO thereover carrying the outer gears 11 for the actuation of" the spindles 13 and carried around by the .sleeves l0 by intermediary of friction springs 17. The sleeves 10 are held .by screws 16 in their positions` onthe shafts 9. .The ball bearings`7 result in an exact ycentering of the beam Vsections whereby a precise running of lthe shaft 9. is obtained.y

The ballbearings are vforming the only interconnection' of the inner spaces Aof the beams andv the connection thereof tov the outside, so that theexit `of'voil, and theentrance of'fdust is to a considerable extent prevented. In order to still'better obtain this purpose the bore 6 for'the ball v,bearing is not 4completely passing throughthe endY faces 1,1. 2, so that the members 12 are leftA laterally covering the ball bearings .7.
